ZFS: fix adding vdevs to very large pools

r323791 changed the return value of zpool_read_label.  Error paths that
previously returned 0 began to return -1 instead.  However, not all error
paths initialized errno.  When adding vdevs to a very large pool, errno could
be prepopulated with ENOMEM, causing the operation to fail.  Fix the bug by
setting errno=ENOENT in the case that no ZFS label is found.
